7.5.11 Transducer Setup Menu
The Transducer Setup menu contains settings that does not require frequent
changes.
[MENU] + "TRANSDUCER SETUP" + [ENTER]
Keel Offset : It is the transducer depth offset from the surface. This makes it possible to measure
depth from the surface instead of from the transducer's location.
Calibrate Sound Speed : Allows calibrating the value of Sound Speed in the water, depending on the water
temperature and salinity.
Calibrate Water Speed : Allows calibrating the value of Water Speed sensor. The calibration value, in the
range between -10% to +10%, will be applied to the water speed from the transducer.
Calibrate Water Temp : Allows the calibration on the Water Temperature sensor. Using the readings from a
precise temperature measuring device, insert here a positive/negative offset to
display right value on Fish Finder screens.
Calibrate Aux Temp : Allows the calibration of the Aux Temperature sensor. Using the readings from a
precise temperature measuring device, insert here a positive/negative offset to
display right value on FF screens.
Set Defaults Settings : Restores the default values
7.5.12 Alarms Menu
The Alarms menu allows you to define additional sonar alarm settings for Fish
Alarm, Shallow Alarm, Depth Alarm and Temperature Upper/Lower/Rate.
[MENU] + "ALARMS" + [ENTER]
Shallow Alarm : Triggers an alarm when depth becomes shallower than the value set.
Deep Water Alarm : Triggers an alarm when depth becomes deeper than the value set.
Temp Upper : Triggers an alarm when the transducer reports a temperature (from TEMP 1 sensor) above the
value set.
Temp Lower : Triggers an alarm when the transducer reports a temperature (from TEMP 1 sensor) below the
value set.
Temp Rate : Triggers an alarm when the transducer reports a temperature (from TEMP 1 sensor) variation rate
above the value set.
Fish Alarm : The options for Fish Alarm set the size of the fishes that, if detected by the unit, switches an alarm
to sound. These options are: Off, Small, Medium, Big and Huge. The alarm sounds if the set size
(or bigger) is detected.
7.5.13 Load Settings from User C-Card
Load the complete settings from the User CARD and changes the active menu
settings.
[MENU] + "LOAD SETTINGS FROM USER C-CARD" + [ENTER]
7.5.14 Save Settings to User C-Card
This is useful to avoid the user having to retune up Fish Finder after a Clear RAM
operation or a software update.
[MENU] + "SAVE SETTINGS TO USER C-CARD" + [ENTER]
7.5.15 Restore Current Preset Defaults
Restores the default values only for the current presets (see Par. 7.5.1, Preset
Mode) and does not affect the other presets.
[MENU] + "RESTORE CURRENT PRESET DEFAULTS" + [ENTER]
7.6 TRANSDUCERS
The transducer is a device that transmits and receives sound waves into the
water. The active component inside the transducer is commonly referred to as an
element but actually is a piezoelectric ceramic material.
Please refer to your dealer and/or installer to choose your transducer. VDO sug-
gest transducers.
